Problems solved by technology

[0002] The contact switch is a circuit switch used on the gas stove valve assembly for pulse ignition of the burner. It is characterized by low cost and wide application. Conducting electrical conduction between them, so there is a phenomenon of poor contact during ignition
In addition, poor plating or corrosion of any of these parts will cause poor electrical conductivity; and due to the gap fit of the parts, the conduction current here is unstable, and the conductive resistance will be relatively large

Embodiment Construction

[0021] The following descriptions are only preferred embodiments embodying the principles of the present invention, and do not therefore limit the protection scope of the present invention

[0022] Such as Figures 1 to 4 Shown is a pulse ignition gas stove valve contact switch of the present invention, which includes a valve seat 5 and a valve body 1, the valve seat 5 and valve body 1 are interlocked together to form a contact switch housing, The valve seat 5 and the valve body 1 are clamped with a fixed contact piece 3, the torsion bar 7 is movably inserted in the contact switch housing and one end passes through the valve seat 5, and the torsion bar 7 is equipped with a moving contact piece 4. Several protruding contacts 31 are distributed on the side of the fixed contact piece 3 opposite to the movable contact piece 4 .

[0023] In this embodiment, three hemispherical protruding contacts 31 are molded on the fixed contact piece 3, and the three hemispherical protruding co...

Abstract

The invention discloses a pulse ignition contact piece switch used for a gas stove valve, which comprises a valve seat (5) and a valve body (1), wherein the valve seat (5) and the valve body (1) are mutually buckled to form a contact piece switch shell; a fixed contact piece (3) is mounted between the valve seat (5) and the valve body (1) in a clamping way; a torsion bar (7) is movably inserted in the contact piece switch shell and one end of the torsion bar penetrates out of the valve seat (5); a movable contact piece (4) is mounted on the torsion bar (7); and a plurality of raised contact points (31) are distributed on the opposite surfaces of the fixed contact piece (3) and the movable contact piece (4). The invention has the characteristics that electric conduction is relatively stable, and conduction resistance is small.

Description

Technical field: [0001] The invention relates to the technical field of contact switches, in particular to a contact switch for pulse ignition gas stove valves. Background technique: [0002] The contact switch is a circuit switch used on the gas stove valve assembly for pulse ignition of the burner. It is characterized by low cost and wide application. There is electrical conduction between them, so there is a phenomenon of poor contact during ignition. In addition, poor plating or corrosion of any of these parts will cause poor electrical conductivity; and due to the clearance fit of the parts, the conduction current here is unstable, and the conductive resistance will be relatively large. Invention content: [0003] The object of the present invention is to provide a pulse ignition gas stove valve contact switch, which has the characteristics of more stable electric conduction and small conduction resistance. [0004] In order to achieve the above object, a pulse igni...
